7 Claims.

My invention relates to improvementsin plows andmore particularly toplows of'the sweep type.

One of the principal objects of my invention is to provide a plow of theabove described character embodying a construction and arrangement whichis such that the sweep may be conveniently adjusted with respect to theshare and to operate at any desired angle or inclination with respect tothe body.

' Another object of my invention is to provide a plow of the abovedescribed character. embodying novel means for adjustably and releasablysecuring the sweep to the body of the plow.

A further object of my invention is to provide a plow of the abovedescribed character which is simple in construction, durable in use,eiiicient in operation and economical in manufacture.

Other objects and advantages will be apparent from the followingdescription, appended claims and annexed drawings.

Referring to the drawings wherein like reference characters designatelike parts throughout the several views:

Figure 1 is a perspectiv view of my invention.

Figure 2 is a bottom plan view thereof partly in section.

Figure 3 is a vertical longitudinal sectional vlew'of the plow.

Figure 4 is a detail sectional view taken on the line 4-4 of Figure 3.

Figure 5 is a perspective view of my novel form of plow but illustratingthe same as having a modified form of sweep attached thereto.

Figure 6' is a perspective view of the plow illustrating the sameprovidedwith a mold-board;

Referring now to the drawings in detail it will be seen that theembodiment of the invention which has been illustrated in Figures 1 to 4inclusive comprises a beam 5 fashioned on the rear end with anarcuate-shaped stock 6, the lower end of which is connected by means ofupper and lower bolts 1 and 8 respectively to the inner face of the body9. The forward end of the body is formed with a frog Hi to which is immovably fixed thereto a share II by means of a bolt and nut I2, saidbolt being fashioned with a squared head seated within a like shapedsocket fashioned in the outer face of the share.

The outer face of the body 9 adjacent the lower edge thereof has securedthereto a landside I3 by means of front and rear bolts l4 and I5respectively. The bolt 14 extends transversely through the body 9adjacentthe rear end of the frog l0 and has pivoted thereon; a lowercorner of an adjusting plate Hi, the latter being fashioned with innerand outer angularly disposed sections IT and I8 respectively. The innersection I! is disposed in substantial parallelism with the inner face ofthe body and has fixed thereto by means of bolts and nuts IS the lowerend of a lever 20, the upper end, of the latter.

opposite end of said bar 25 is connected to the stock 6 in proximity tothe body 9 by means of the upper bolt I.

The upper end of the lever 20 has pivoted thereto a finger-piece 26, thelatter being connectedrto the upper end of the pawl 22 by means of alink 21, whereby operation of the fingerpiece 26" towards the upper endof the lever serves to disconnect the pawl 22 with the rack bar 25 andpermit adjustment of, the lever with respect to the body 9. Obviously,adjustment of the lever 20 serves to effect a similar adjustment of theplate IS.

The outer section it. of the plate it is provided with a series ofspaced apertures 28 through a pair of which extend bolts 29 and whichconnect to said plate 1.6 a sweep 30, it being understood that the sweep3!! is employed in lieu of the ordinary fixed mold-board in a plow ofordinary construction. By extending the bolts 29 through various pairsof the openings 28 adjustment of the sweep 3!! may be had with respectto the plate IS.

The rear end of the body 9 has attached thereto the lower end of a fork3!, the upper end of which is fashioned with a pair of upwardly andoutwardly diverging arms 32 to which are connected the lower ends of theplow handles 33. Rear ends of braces 34 are connected to the plowhandles 33 above the arms 32 and have their forward ends connected tothe beam 5 through the medium of th bolt 26 whereby to reenforce thestructure.

From the foregoing it will be apparent that the sweep 3!] may beadjusted relative to the body and to the share H through the medium ofthe lever 20 thereby permitting a desired amount of soil to be rowedabout plants, for instance tobacco during cultivation thereof.Furthermore, when the plow is being operated over inclined ground, thesweep 30 may be readily adjusted at the end of each row to efiectdisplacement of substantially the same amount of soil from a furrow whenthe plow is operated in a reverse direction.

As illustrated in Figure of the drawings a combined mold-board and sweep40 may be attached tothe plate l6 for adjustment relative to the shareH. In instances where a sweep is not adapted for use, a mold-board 50may be attached to the plate I6 and in fixed relation to the share II asclearly illustrated in Figure 6 of the drawings, it being understoodthat the lever 20 is moved to a position with respect to the bar 25 topreclude operation of the mold-board 50 and that the front end of thelatter snugly fits within the rear end of the shaft to preclude relativemovement therewith.

It is obvious that the invention is not confined to the herein describeduse therefor as it may be utilized for any purpose to which it isadaptable. It is therefore to be understood that the invention is notlimited to the specific construction as illustrated and described, asthe same is only illustrative of the principles of operation, which arecapable of extended application in advance forms, and that the inventioncomprehends all construction within the scope of the appended claims.

I claim:

1. In a plow structure, comprising a body, a share immovably fixed tosaid body, a land-side carried by the body, a sweep adjustably securedto a plate of angular form, and means for pivotally connecting andadjusting said plate on the body.

2. In a plow structure, comprising a body, a share immovably fixed tosaid body, a landside carried by the body, a plate pivotally carried bythe body and having an angular portion extending rearwardly with aseries of openings, a rearwardly extending sweep secured by bolts withinthe angular portion for vertical adjustment, and a lever adapted to movesaid pivoted plate for raising and lowering the free end of I the sweep.I

3. In a plow structure, comprising a body, a share immovably fixed tosaid body, a land-side carried by the body, a vertically disposed platepivotally secured at its lower end to the body and having an angularportion extending rearwardly on the opposite side from the land-side,said plate having a series of transverse openings, a rearwardlyextending sweep secured by bolts through said openings for verticaladjustment of the sweep thereon, a lever rigidly connected to the plateabove the pivotal connection thereof with the body, and means forholding said lever in its adjusted position.

4. A plow construction comprising a body portion, a share fixed thereto,a support pivotally attached to the body portion adjacent the share,said support having a plane surface and a turning axis intersecting theplane surface at an acute angle thereto, a sweep secured to the planesurface of the support, means to permit change of the relative angularposition of the sweep with respect to the support, and additional meansto change the position of the support with respect to the body portion.5.- A plow construction comprising a body portion, a share fixedthereto, a support pivotally tion, a share fixed thereto, a supportpivotally attached to the body portion adjacent the share,

said support having a plane surface and a tuming axis intersecting theplane surface at an acute angle thereto, a sweep secured to the planesurface of the support, means to permit change of the relative angularposition of the sweep with respect to the support, a lever rigidlyattached to the support whereby the position of the support with respectto the body portion may be changed, and releasable detent meansassociated with the lever for inhibiting change of position of thesupport with respect to, the body portion.

7. A plow construction comprising a body portion, a share fixed thereto,a support pivotally attached to the body portion adjacent the share,

said support having a plane surface and a turning axis which intersectsthe lower edge of the plane surface if, an angle thereto, a sweepattached adjacent one of its ends to the plane surface of the supportand forming thereby a continuation of the share, means to permit changeof the relative angular position of the sweep with respect to thesupport and additional means to move the support about its turning axisto change the relative angular position of the sweep with respect to thebody portion.
